It's a good little app, however as with every application/product which claims or is touted to be a something "Killer" ... it's just not. It can certainly stand on it's own two feet, but it wont be replacing photoshop on desktops across the globe.
I like it, and will likely be using it more and more for smaller image tweaks simply because using photoshop for such things is unnecessary, though for those small tweaks (Rei-sizing, adding text, etc.) I've become quite attached to Skitch.
EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
